For the first communication ever since a cell phone, Martin Cooper, Motorola Research Director, chose to call Joel Engel, his counterpart and rival in Bell Labs, the research laboratory of the U.S. telecommunications AT & T giant "I gave several calls in the street that day, including a reporter from a New York radio, which I talked through the street.". "Probably one of the things more dangerous that I ever made in my life", tell Martin Cooper a few years later. Still need to wait ten years before Motorola sells his first cell phone. Launched in Chicago by Ameritech, first American commercial mobile service, the DynaTAC... weighed a pound and cost $ 3,500!
The US late
Today, the global mobile telecommunications market has more subscribers than the traditional telecommunications. Fills the irony, the United States are still struggling to historic technological catch on the rest of the world. The concept of the cell phone was born in 1947, when AT & T Researchers realized that the mobile phone installed in police vehicles had the potential for a commercial application. It was sufficient to reduce the extent of the ("cell") area served by each radio transmitter to multiply the number of cells, and broaden the spectrum of radio frequencies allocated to telecommunications. Twenty years later, the Federal Communications Commission (FCC) is decided, finally, to expand mobile telecommunications frequency allocations, on condition however that industry demonstrates the viability of the technology. The private sector expected that it to invest in research. And in 1982 the FCC authorizes the development of a commercial service in the United States. The rest of the world had taken the lead.
GSM networks
It was in 1979 that is launched the first commercial mobile service in the world. But it is in Europe that was to decide the future of the mobile. In 1981, the first multinational mobile network of first generation (1 G), Nordisk Mobil Telefon (NMT), was deployed in Scandinavia, before be extended in some 30 countries. In the 1980s, the development in Europe of the common standard of GSM digital technology has completed digging the gap between the US and the rest of the world. About 80 of the global mobile market, or more than 3 billion users, dependent on GSM networks, so-called second generation (2 G). Introduced in the United States only in 1996, this technology has long remained minority in the US market. However, from the beginning, it allowed operators to enhance their mobile service of a new feature: the exchange of text, or SMS. Soon SMS became the main source of income for the operators, to voice communications, and thus an essential criterion for the design of phones. The American manufacturer Motorola has ignored this factor at its peril. While the Nokia Finns weighs 36.2 of the world market for mobile phones, Motorola fourth-place with only 6.2 of the market. By contrast, the Canadian Research In Motion (RIM), maker of the BlackBerry, has recently adopted the SMS technology to take off from the North American market. He currently holds the highest rate of growth in the industry. He sold as many BlackBerry in the fourth quarter of 2008 than during its first five years of exercise. The industry now has the eyes fixed on the next generation of phones that integrate services and Web applications, or "smartphones". On the year, the firm IDC anticipates a decline of 1.9 of mobile phones and an increase of 8.9 of "smartphones".
Innovation has found the way of the United States, since the transformation of the cell phone in a minicomputer gives the advantage of actors from the computer industry. With the iPhone, Apple has produced a GSM phone with both a large screen, to appeal to the US market, and a keyboard that is ideally suited to the SMS, to seduce the rest of the world. Remains to be seen how the Palm Pre, also developed in Silicon Valley, will be introduced into the breach.
